What is the purpose of grounding in electrical systems?

Grounding in electrical systems serves primarily to prevent electrical shock hazards. This safety measure involves creating a direct physical connection to the earth or a reference point in the electrical system. By doing so, any fault current that may arise from equipment failure or accidental contact is directed safely away from individuals and sensitive equipment.

When a fault occurs, such as a short circuit, the grounding system provides a low-resistance path for the fault current to flow, which helps to trip circuit breakers or blow fuses. This rapid disconnection of the electrical supply minimizes the risk of electric shock and reduces the possibility of fire hazards caused by electrical faults.

While grounding contributes to the overall stability and reliability of electrical systems, its primary purpose remains focused on safety: protecting people from accidental electrical shocks and enhancing the overall safety of electrical installations.
